Here's a sample session to show how to use this module.
At the moment, this is the only documentation.

The Basics
----------

Importing is easy...

   >>> from http import cookies

Most of the time you start by creating a cookie.

   >>> C = cookies.SimpleCookie()

Once you've created your Cookie, you can add values just as if it were
a dictionary.

   >>> C = cookies.SimpleCookie()
   >>> C["fig"] = "newton"
   >>> C["sugar"] = "wafer"
   >>> C.output()
   'Set-Cookie: fig=newton\r\nSet-Cookie: sugar=wafer'

Notice that the printable representation of a Cookie is the
appropriate format for a Set-Cookie: header.  This is the
default behavior.  You can change the header and printed
attributes by using the .output() function

   >>> C = cookies.SimpleCookie()
   >>> C["rocky"] = "road"
   >>> C["rocky"]["path"] = "/cookie"
   >>> print(C.output(header="Cookie:"))
   Cookie: rocky=road; Path=/cookie
   >>> print(C.output(attrs=[], header="Cookie:"))
   Cookie: rocky=road

The load() method of a Cookie extracts cookies from a string.  In a
CGI script, you would use this method to extract the cookies from the
HTTP_COOKIE environment variable.

   >>> C = cookies.SimpleCookie()
   >>> C.load("chips=ahoy; vienna=finger")
   >>> C.output()
   'Set-Cookie: chips=ahoy\r\nSet-Cookie: vienna=finger'

The load() method is darn-tootin smart about identifying cookies
within a string.  Escaped quotation marks, nested semicolons, and other
such trickeries do not confuse it.

   >>> C = cookies.SimpleCookie()
   >>> C.load('keebler="E=everybody; L=\\"Loves\\"; fudge=\\012;";')
   >>> print(C)
   Set-Cookie: keebler="E=everybody; L=\"Loves\"; fudge=\012;"

Each element of the Cookie also supports all of the RFC 2109
Cookie attributes.  Here's an example which sets the Path
attribute.

   >>> C = cookies.SimpleCookie()
   >>> C["oreo"] = "doublestuff"
   >>> C["oreo"]["path"] = "/"
   >>> print(C)
   Set-Cookie: oreo=doublestuff; Path=/

Each dictionary element has a 'value' attribute, which gives you
back the value associated with the key.

   >>> C = cookies.SimpleCookie()
   >>> C["twix"] = "none for you"
   >>> C["twix"].value
   'none for you'

The SimpleCookie expects that all values should be standard strings.
Just to be sure, SimpleCookie invokes the str() builtin to convert
the value to a string, when the values are set dictionary-style.

   >>> C = cookies.SimpleCookie()
   >>> C["number"] = 7
   >>> C["string"] = "seven"
   >>> C["number"].value
   '7'
   >>> C["string"].value
   'seven'
   >>> C.output()
   'Set-Cookie: number=7\r\nSet-Cookie: string=seven'
